| 中文摘要: |
| 以成熟的野生柳叶蜡梅种子为材料，采用超声波辅助法提取籽油，测定籽油的理化性质、维生素E含量和脂肪酸组成，并以ABTS自由基清除作用和金属离子螯合作用为指标评价籽油的抗氧化活性。结果表明：野生柳叶蜡梅籽油酸价（KOH）为2.28 mg/g、碘值（I）为109.47 g/100 g、过氧化值为2.03 mmol/kg、皂化值（KOH）为185.81 mg/g、水分及挥发物为0.82%、相对密度（20 ℃）为0.927 5、折光指数（20 ℃）为1.467 3、维生素E含量为109.27 mg/kg；从野生柳叶蜡梅籽油中共鉴定出22种脂肪酸，包括8种饱和脂肪酸（24.28%）和14种不饱和脂肪酸（75.37%），含量较高的脂肪酸有亚油酸（55.60%）、棕榈酸（20.26%）、油酸（8.08%）、10,13-十八碳二烯酸（8.02%）；野生柳叶蜡梅籽油具有良好的抗氧化活性，对ABTS自由基清除效果优于葡萄籽油，对金属离子螯合作用弱于葡萄籽油。 |
| 英文摘要: |
| With the mature seed of wild Chimonanthus salicifolius Hu as raw material, the seed oil was obtained by ultrasound-assisted extraction. The physicochemical properties, VE content and fatty acid composition of wild Chimonanthus salicifolius Hu seed oil were determined. The antioxidant activities of wild Chimonanthus salicifolius Hu seed oil were also evaluated by scavenging capacity against ABTS free radical and metal ions chelating ability. The results showed that the acid value, iodine value, peroxide value, saponification value, moisture and volatiles, relative density(20 ℃), refractive index (20 ℃) and vitamin E content of wild Chimonanthus salicifolius Hu seed oil were 2.28 mgKOH/g, 109.47 gI/100 g, 2.03 mmol/kg, 185.81 mgKOH/g, 0.82%, 0.927 5, 1.467 3 and 109.27 mg/kg, respectively. Twenty-two kinds of fatty acids were identified from wild Chimonanthus salicifolius Hu seed oil including eight kinds of saturated fatty acids (24.28%) and fourteen kinds of unsaturated fatty acids (75.37%). The main fatty acids were linoleic acid (55.60%), palmitic acid (20.26%), oleic acid (8.08%), and 10,13-octadecadienoic acid (8.02%). The wild Chimonanthus salicifolius Hu seed oil had good antioxidant activities, and its scavenging capacity against ABTS free radical was better than that of grape seed oil, while the metal ions chelating ability was weaker than that of grape seed oil. |
